Astrophysics is primarily an observational science. Since the objects of study are beyond the reach of direct physical experimentation, it is essential to develop telescopes and the instruments that equip them to gather data about the universe. Astrophysical questions drive the choices made in instrument design and usage, from construction to operation.
The questions scientists pose in astrophysics are boundless, but numerous constraints exist when seeking answers. These challenges range from the limits of fundamental physics and the difficulties of ground- or space-based observations, to technological restrictions, budgetary concerns, and the time required for implementation.
This course aims to bridge the gap between scientific inquiries and the development of suitable, feasible instrumental solutions and to help students gain a deep understanding of the observational and instrumental challenges in astrophysics. While it is not an engineering course, it emphasizes how to address scientific questions through the design of appropriate instruments, ultimately preparing students for the role of an 'Instrument Scientist.' This role requires a strong grasp of both the scientific problems and the instrumental requirements, allowing for effective collaboration with engineers to create the necessary tools for astrophysical research. An 'Instrument Scientist' bridges the gap between science and engineering. They possess a deep understanding of both the scientific problem and the necessary instrumental requirements, enabling them to provide the best options to engineers who will design the instrument.
